This change renames Class::is_cycle_free to Class::is_declaration_loaded
and under the hood replaces cycle_free and type_finalized bits with
class loading state enum.
Also, added new assertions to check is_declaration_loaded().

This work pulls in v8 support for these features with
appropriate changes for Dart and closes
https://github.com/dart-lang/sdk/issues/34935.
This adds support for the following features:
* Interpreting patterns as Unicode patterns instead of
BMP patterns
* the dotAll flag (`/s`) for changing the behavior
of '.' to also match line terminators
* Escapes for character classes described by Unicode
property groups (e.g., \p{Greek} to match all Greek
characters, or \P{Greek} for all non-Greek characters).
The following TC39 proposals describe some of the added features:
* https://github.com/tc39/proposal-regexp-dotall-flag
* https://github.com/tc39/proposal-regexp-unicode-property-escapes
These additional changes are included:
* Extends named capture group names to include the full
range of identifier characters supported by ECMAScript,
not just ASCII.
* Changing the RegExp interface to return RegExpMatch
objects, not Match objects, so that downcasting is
not necessary to use named capture groups from Dart
**Note**: The changes to the RegExp interface are a
breaking change for implementers of the RegExp interface.
Current users of the RegExp interface (i.e., code using Dart

Currently internal cids for all element sizes are packed together, so
are external cids and view cids.
This change re-orders them to make internal/external/view for the same
element size be packed together.
This allows is/as checks for those classes to be performed with
continuous cid-range check. For example "<obj> is Uint8List" becomes
one range check.
(For most applications internal/external/view classes are the only
non-abstract implementations of those interfaces)

This moves the length field as well as an inner pointer to the start of
the data into the RawTypedDataBase class. The inner pointer is updated
on allocation, scavenges and old space compactions.
To avoid writing more assembly the typed data view factory constructors
will be generated using IL, which will update the inner pointer. This
required adding new IR instructions and changing the existing
UnboxedIntConverter instruction.
This is the foundation work to de-virtualize calls on the public typed
data types, e.g. Uint8List.

This change replaces kernel AST declarations of fields and functions

Startup latency:
Time to the first full frame: 1.945s -> 1.687s
FinalizeClass: 554ms -> 277ms
FinishClassLoading: 296ms -> 156ms
There are following regressions in bytecode mode, which will be fixed
in future:
* dart:mirrors are not supported yet (implementation of mirrors relies
on reading kernel AST in certain cases).
As the result, lib_2/mirrors/* tests fail.
* native extensions are not supported yet (annotations on libraries
and classes in AST are cleaned up as they could reference members
which are now removed from AST).
As the result, standalone_2/entrypoints_verification_test test fails.
* language_2/spread_collections/const_error_test/* tests fail
due to https://github.com/dart-lang/sdk/issues/36286.

See https://github.com/tc39/proposal-regexp-named-groups
for a high-level description of the feature and examples. This is one of the
features requested in https://github.com/dart-lang/sdk/issues/34935.
This is a partial implementation because while there is a way to retrieve
groups via Dart by name, it requires casting the returned Match to the
new RegExpMatch interface to avoid changing the RegExp interface.
Changing the RegExp interface will happen in a future update, since there
are other planned changes to the RegExp interface coming soon and that way
we only change it once. See https://github.com/dart-lang/sdk/issues/36171
for more details on the planned changes.
Also, since only BMP regular expressions are supported, not full
Unicode ones (i.e., those with the /u flag in ECMAscript), \k<NAME>
will only be parsed as a named back reference if there are named
captures in the string. Otherwise, the \k will be parsed as the identity
escape for backwards compatibility. The new tests illustrate this
difference.

This removes the 3 fields from the classes in Dart and instead describes
the layout in C++ via a RawTypedDataView class (as already do with
normal RawTypedData). The existing "semi" TypedDataView handle class is
changed to be a real handle class.
This decreases performance of some microbenchmarks due to field guards
not being used anymore (before the JIT could add a field guard to view classes
guarding that only normal typed data is used as backing store (and not e.g. external
typed data)

For all non-generic classes the AllocateObject runtime call would not
guarantee that the returned object is new or marked as remembered. If
such an object is subject to a store with an eliminated write-barrier,
we have incorrect remembered set, which causes flaky crashes.
This CL fixes the AllocateObject runtime call to always ensure the
object is new or added to the remembered set if write-barrier
elimination is enabled for those.
Furthermore the conditions for when the write barrier can be eliminated
is centralized in one place instead of duplicated (in runtime_entry.cc
and il.h) to avoid future divergence of the two.
Similarly the condition to when an array uses card marking is put into
one place.

This is the next step towards preventing compiler from directly peeking
into runtime and instead interact with runtime through a well defined
surface.
This CL decouples the hand-written stub codes from the runtime. The
target architecture dependent stubs are moved to
dart::compiler::StubCodeCompiler which use dart::compiler::target:*
for accessing any runtime related code.
The generation of type testing stubs is moved to separate files for the
time being.
